Machine Translation tasks must tackle the ever-increasing sizes of parallel corpora, requiring space and time efficient solutions to support them. Several approaches were developed based on full-text indices, such as suffix arrays, with important time and space achievements. However, for supporting bilingual tasks, the search time efficiency of such indices can be improved using an extra layer for the text alignment. Additionally, their space requirements can be significantly reduced using more compact indices. We propose a search procedure on top of a compact bilingual framework that improves bilingual search response time, while having a space efficient representation of aligned parallel corpora.
